Objective – The project was sponsored by Overseer Limited, the Foundation for Arable Research (FAR) and the Vegetable Research and Innovation Board (represented by Horticulture New Zealand). The project was undertaken by the New Zealand Institute for Plant & Food Research Limited (PFR).

The assessment was done by comparing OVERSEER estimates with estimates generated by a modified version of the Agricultural Production Systems sIMulator (SCRUM-APSIM).

Project completed – Final report received – While some results align, the final report identifies differences in the two data sets, suggesting OVERSEER is not behaving as expected for all crops. The reason for these differences cannot be clearly identified using whole model outputs. Further investigation is needed to pinpoint the changes required for OVERSEER
